外耳道

Repeated stimulation by cold water is usually the cause of exostosis and this has been well report in patients who regularly swim or surf in cold water. Other activities that inducing exostosis such as taking a sauna have been less reported.

有关外耳道外生骨疣的报告，患者大都是长时间在冷水游泳或冲浪等活动引起的，因三温暖活动头部浸泡冷水引起的情形则没被报告过。

They were treated with surgical operation, radical therapy and chemistry therapy.Results Diagnosis of sebaceous carcinoma demanded immunohistochemistry, and rare parotid sebaceous carcinoma was still distinguished with clear cell carcinoma, grume epidermis carcinoma and acinic cell carcinoma in pathology.

收集28例经病理证实的头颈部皮脂腺癌患者的临床资料，其中眼睑皮脂腺癌10例；腮腺皮脂腺癌2例；外耳道皮脂腺癌5例；颌面部皮脂腺癌7例；颈部皮脂腺癌4例，颈部淋巴结转3例，采用手术、放疗、化疗等综合治疗。

Reconstruction of acusticus back wall and hearing after radical mastoidectomy with homograft costal cartilage is effective to prevent mastoid cavity infection and improve hearing.

以同种异体肋软骨对乳突根治术后耳行外耳道后壁及听力重建术，是防止乳突腔感染，提高听力的较理想方法。

Results: The satisfactory MPR images of cochlea, bony semicircular canals, internal auditory meatus and other intratemporal structures can be obtained. The SSD images could show some important bony marks of temporal bone and spatial relationships between them clearly. On coronal plane, SSD images can vividly demonstrate the shape and spatial relationships of malleus and incus. A series images were obtained as the virtual endoscope moved from the external auditory canal to the middle ear cavity.

结果：MPR能在不同切面显示耳蜗、半规管、内耳道及面神经管垂直段等结构，显示率为100%；SSD能清晰显示颞骨重要的骨性结构，如内耳门、颈静脉孔等，冠状位切割后的SSD图像能生动地显示锤骨、砧骨的立体形态及空间关系；CTVE可模仿内窥镜从外耳向中耳移动，清晰显示骨性外耳道、鼓室内侧壁及听骨链等结构。

It was first reported in 1978 by Kemp by placing a earphone-micphone probe in the ear canal.

它首次由英国人Kemp在1978年通过放人外耳道的耳机一话筒组合探头检测到。

Objective: To reconstruct middle ear structure for open mastoid antrum with external auditory canal after radical mastoidectomy in one-stage.

目的：为使乳突根治术后耳向外耳道开放的乳突腔重新中耳化和一期行听力重建。

One case with necrotizing external otitis was treated with radical mastoidectomy and antibiotic.
